Flight Conducted Under: Part 91: General aviation - Personal

On August 6, 2021, about 1620 central daylight time, an Cubcrafters, CC11-160, N825ME, was substantially damaged when it was involved in an accident near Springfield, Tennessee. The airline transport pilot and pilot-rated passenger were not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

The pilot stated that after refueling with 18 gallons of aviation fuel, they took off from Springfield Robertson County Airport (M91) Springfield, Tennessee, and flew to a private airport about 10 nautical miles southeast. The airplane was performing well and there were no indications or anomalies observed during the flight. After landing and coming to a full stop at the airport, they conducted another takeoff, flew a normal traffic pattern, then conducted a touch-and-go. During the subsequent climb, about 400 ft above ground level, the engine suddenly stopped producing power; “there was no sputter or indication, it just stopped.” There was little time to troubleshoot as they were descending “quickly” and performed a forced landing in a field. Upon landing, the airplane struck a fence then touched down, which collapsed the landing gear before coming to rest.

Examination of the airframe and engine by a Federal Aviation Administration inspector (FAA) revealed that the airplane sustained substantial damage to the fuselage and wings. The fuel tank contained aviation fuel that was clean and free of debris. There was oil in the engine reservoir and no debris or metallic material in the oil filter. The electronic ignition system produced spark on all spark plug electrodes. The FAA inspector performed a download of the Electronic Flight Instrument System. A preliminary review of the engine and performance data indicated that at an altitude of about 1,000 ft mean sea level, while climbing about 1,000 ft per minute at a groundspeed of 80 kts, the engine rpm, oil pressure, and exhaust gas temperatures suddenly decreased, followed shortly by a decrease in fuel flow. There were no associated crew-alerting system alerts recorded during the flight.

The airplane was retained for further examination.
